Summary

0001157: class loader enhancement for JPA

Description

(rep by Costin Leau)

I have basically two questions - feel free to add any information you
think it's relevant:

1. a very important issue would be cloning classloaders (basically the
getNewTempClassLoader() from JPA) - a way to get a new instance of a
classloader that is configured exactly like the initial one. The
instance would be then instructed to have code
enhancement/transformation off and it will be used to load classes just
like the original one.
I've seen that EnvironmentClassLoader has a protected replace() method -
is this a good way to clone classloaders or can you recommend another one?
Will such a feature make it into a future release of resin?

2. by default, Resin classloaders (DynamicCL & co) support only one
ByteCodeEnhancer - does Resin support some sort of chaining Enhancer so
one can actually add an enhancer instead of overriding the existing one?
